INSTALLATION STEP 10Install The Protector System®

The safety reversing sensor must be connectedand aligned correctly before the garage dooropener will move in the down direction.

IMPORTANT INFORMATION ABOUT THE SAFETY REVERSING SENSORWhen properly connected and aligned, the sensorwill detect an obstacle in the path of its electronicbeam. The sending eye (with an orange indicatorlight) transmits an invisible light beam to thereceiving eye (with a green indicator light). If anobstruction breaks the light beam while the door isclosing, the door will stop and reverse to full openposition, and the opener lights will flash 10 times.

The units must be installed inside the garage so thatthe sending and receiving eyes face each otheracross the door, no more than 6" above the floor.Either can be installed on the left or right of the dooras long as the sun never shines directly into thereceiving eye lens.

The mounting brackets are designed to clip onto thetrack of sectional garage doors without additionalhardware.

If it is necessary to mount the units on the wall, thebrackets must be securely fastened to a solidsurface such as the wall framing. Extension brackets(see accessories) are available if needed. If installingin masonry construction, add a piece of wood ateach location to avoid drilling extra holes in masonryif repositioning is necessary.

The invisible light beam path must be unobstructed.No part of the garage door (or door tracks, springs,hinges, rollers or other hardware) may interrupt thebeam while the door is closing.

• Be sure power is not connected to the garage dooropener BEFORE installing the safety reversing sensor.

• To prevent SERIOUS INJURY or DEATH from a closinggarage door:– Correctly connect and align the safety reversing

sensor. This required safety device MUST NOT bedisabled.

– Install the safety reversing sensor so beam is NOHIGHER than 6" above garage floor.

INSTALLING THE BRACKETSBe sure power to the opener is disconnected.Install and align the brackets so the sensors will faceeach other across the garage door, with the beam nohigher than 6" above the floor. They may be installedin one of three ways, as follows.

Garage door track installation (preferred):• Slip the curved arms over the rounded edge of

each door track, with the curved arms facing thedoor. Snap into place against the side of the track.It should lie flush, with the lip hugging the backedge of the track, as shown in Figure 1.

If your door track will not support the bracketsecurely, wall installation is recommended.

Wall installation:• Place the bracket against the wall with curved

arms facing the door. Be sure there is enoughclearance for the sensor beam to be unobstructed.

• If additional depth is needed, an extension bracket(see Accessories) or wood blocks can be used.

• Use bracket mounting holes as a template tolocate and drill (2) 3/16" diameter pilot holes onthe wall at each side of the door, no higher than 6"above the floor.

• Attach brackets to wall with lag screws(not provided).

• If using extension brackets or wood blocks, adjustright and left assemblies to the same distance outfrom the mounting surface. Make sure all doorhardware obstructions are cleared.

Floor installation:• Use wood blocks or extension brackets (see

Accessories) to elevate sensor brackets so thelenses will be no higher than 6" above the floor.

• Carefully measure and place right and leftassemblies at the same distance out from the wall.Be sure all door hardware obstructions arecleared.

• Fasten to the floor with concrete anchors asshown.

Figure 4MOUNTING AND WIRING THE SAFETY SENSORS• Slide a 1/4"-20x1/2" carriage bolt head into the slot

on each sensor. Use wing nuts to fasten sensors tobrackets, with lenses pointing toward each otheracross the door. Be sure the lens is not obstructedby a bracket extension (Figure 4).

• Finger tighten the wing nuts.

• Run the wires from both sensors to the opener. Useinsulated staples to secure wire to wall and ceiling.

• Strip 7/16" of insulation from each set of wires.Separate white and white/black wires sufficiently toconnect to the opener quick-connect terminals.Twist like colored wires together. Insert wires intoquick-connect holes: white to white and white/blackto grey (Figure 5).

ALIGNING THE SAFETY SENSORS• Plug in the opener. The indicator lights in both the

sending and receiving eyes will glow steadily ifwiring connections and alignment are correct.

The sending eye orange indicator light will glowregardless of alignment or obstruction. If the greenindicator light in the receiving eye is off, dim, orflickering (and the invisible light beam path is notobstructed), alignment is required.

• Loosen the sending eye wing nut and readjust,aiming directly at the receiving eye. Lock in place.

• Loosen the receiving eye wing nut and adjustsensor until it receives the sender’s beam. Whenthe green indicator light glows steadily, tighten thewing nut.

TROUBLESHOOTING THE SAFETY SENSORS1. If the sending eye indicator light does not glow

steadily after installation, check for:

• Electric power to the opener.

• A short in the white or white/black wires. Thesecan occur at staples, or at opener connections.

• Incorrect wiring between sensors and opener.

• A broken wire.

2. If the sending eye indicator light glows steadily butthe receiving eye indicator light doesn't:

• Check alignment.

• Check for an open wire to the receiving eye.

3. If the receiving eye indicator light is dim, realigneither sensor.

NOTE: When the invisible beam path is obstructed ormisaligned while the door is closing, the door willreverse. If the door is already open, it will not close.The opener lights will blink 10 times. (If bulbs are notinstalled, 10 clicks can be heard.) See page 17.

INSTALLATION STEP 11Fasten the Door Bracket

Follow instructions which apply to your door typeas illustrated below or on the following page.

A horizontal reinforcement brace should be longenough to be secured to two or three verticalsupports. A vertical reinforcement brace shouldcover the height of the top panel.Figure 1 shows one piece of angle iron as thehorizontal brace. For the vertical brace, 2 pieces ofangle iron are used to create a U-shaped support.The best solution is to check with your garage doormanufacturer for an opener installation doorreinforcement kit.

NOTE: Many door reinforcement kits provide fordirect attachment of the clevis pin and door arm. Inthis case you will not need the door bracket; proceedto Step 12.

SECTIONAL DOORS1. Center the door bracket on the previously marked

vertical centerline used for the header bracketinstallation. Note correct UP placement, asstamped inside the bracket.

2. Position the top edge of the bracket 2"-4" belowthe top edge of the door, OR directly below anystructural support across the top of the door.

3. Mark, drill holes and install as follows, dependingon your door’s construction:

Metal or light weight doors using a vertical angleiron brace between the door panel support andthe door bracket:• Drill 3/16" fastening holes. Secure the door bracket

using the two 1/4"-14x5/8" self-threading screws.(Figure 2A)

• Alternately, use two 5/16" bolts, lock washers andnuts (not provided). (Figure 2B)

Metal, insulated or light weight factory reinforceddoors:• Drill 3/16" fastening holes. Secure the door bracket

using the self-threading screws (Figure 3).

Wood Doors:• Use top and bottom or side to side door bracket

holes. Drill 5/16" holes through the door andsecure bracket with 5/16"x2" carriage bolts, lockwashers and nuts (not provided). (Figure 4)

NOTE: The 1/4"-14x5/8"self-threading screws arenot intended for use onwood doors.

ADJUSTMENT STEP 1Adjust the UP and DOWN TravelLimits

Limit adjustment settings regulate the points at whichthe door will stop when moving up or down.

To operate the opener, press the Door Control pushbar. Run the opener through a complete travel cycle.

• Does the door open and close completely?

• Does the door stay closed and not reverseunintentionally when fully closed?

If your door passes both of these tests, no limitadjustments are necessary unless the reversing testfails (Adjustment Step 3, page 26).

Adjustment procedures are outlined below. Read theprocedures carefully before proceeding toAdjustment Step 2. Use a screwdriver to make limitadjustments. Run the opener through a completetravel cycle after each adjustment. NOTE: Repeated operation of the opener duringadjustment procedures may cause the motor tooverheat and shut off. Simply wait 15 minutes andtry again.

NOTE: If anything interferes with the door’s upwardtravel, it will stop. If anything interferes with thedoor’s downward travel (including binding orunbalanced doors), it will reverse.

HOW AND WHEN TO ADJUST THE LIMITS

• If the door does not open completely but opensat least five feet:Increase up travel. Turn the UP limit adjustmentscrew clockwise. One turn equals 2" of travel.

NOTE: To prevent the trolley from hitting the coverprotection bolt, keep a minimum distance of 2-4"between the trolley and the bolt.

• If door does not open at least 5 feet: Adjust the UP (open) force as explained inAdjustment Step 2.

• If the door does not close completely:Increase down travel. Turn the down limitadjustment screw counterclockwise. One turnequals 2" of travel.

If door still won't close completely and the trolleybumps into the pulley bracket (page 4), trylengthening the door arm (page 22) anddecreasing the down limit.

• If the opener reverses in fully closed position:Decrease down travel. Turn the down limitadjustment screw clockwise. One turn equals 2"of travel.

Without a properly installed safety reversal system,persons (particularly small children) could beSERIOUSLY INJURED or KILLED by a closing garagedoor.• Incorrect adjustment of garage door travel limits will

interfere with proper operation of safety reversalsystem.

• If one control (force or travel limits) is adjusted, theother control may also need adjustment.

• After ANY adjustments are made, the safety reversalsystem MUST be tested. Door MUST reverse oncontact with one-inch high object (or 2x4 laid flat) onfloor.

• If the door reverses when closing and there isno visible interference to travel cycle:If the opener lights are flashing, the SafetyReversing Sensors are either not installed,misaligned, or obstructed. See Troubleshooting,page 19.

Test the door for binding: Pull the emergencyrelease handle. Manually open and close the door.If the door is binding or unbalanced, call for atrained door systems technician. If the door isbalanced and not binding, adjust the DOWN(close) force. See Adjustment Step 2.

ADJUSTMENT STEP 2Adjust the Force

Force adjustment controls are located on the backpanel of the motor unit. Force adjustment settingsregulate the amount of power required to open andclose the door.

If the forces are set too light, door travel may beinterrupted by nuisance reversals in the downdirection and stops in the up direction. Weatherconditions can affect the door movement, sooccasional adjustment may be needed.

The maximum force adjustment range is about3/4 of a complete turn. Do not force controlsbeyond that point. Turn force adjustment controlswith a screwdriver.

NOTE: If anything interferes with the door’s upwardtravel, it will stop. If anything interferes with thedoor’s downward travel (including binding orunbalanced doors), it will reverse.

HOW AND WHEN TO ADJUST THE FORCES1. Test the DOWN (close) force• Grasp the door bottom when the door is about

halfway through DOWN (close) travel. The doorshould reverse. Reversal halfway through downtravel does not guarantee reversal on a one-inchobstruction. See Adjustment Step 3, page 26.If the door is hard to hold or doesn't reverse,DECREASE the DOWN (close) force by turningthe control counterclockwise. Make smalladjustments until the door reverses normally. Aftereach adjustment, run the opener through acomplete cycle.

• If the door reverses during the down (close)cycle and the opener lights aren't flashing,INCREASE DOWN (close) force by turning thecontrol clockwise. Make small adjustments until thedoor completes a close cycle. After eachadjustment, run the opener through a completetravel cycle. Do not increase the force beyond theminimum amount required to close the door.

2. Test the UP (open) force• Grasp the door bottom when the door is about

halfway through UP (open) travel. The door shouldstop. If the door is hard to hold or doesn't stop,DECREASE UP (open) force by turning the controlcounterclockwise. Make small adjustments until thedoor stops easily and opens fully. After eachadjustment, run the opener through a completetravel cycle.

• If the door doesn’t open at least 5 feet,INCREASE UP (open) force by turning the controlclockwise. Make small adjustments until dooropens completely. Readjust the UP limit ifnecessary. After each adjustment, run the openerthrough a complete travel cycle.
